• Performing a fuzzy search may retrieve terms with similar spellings: wing ((yan yang) OR (dan yang)) du huang ying jin ((zhong zhi) or (hong g)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wing ((yan yang) OR (dan yang)) du huang ying jin ((zhong zhi) OR (hong g)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yan yang) OR (dan yang)) du huang ying jin ((zhong zhi) or (hong g)) ;".
• Adding a wildcard symbol may retrieve word variants: wing ((yan yang) OR (dan yang)) du huang ying jin ((zhong zhi) or (hong g)) ;*.
